Building Construction Techniques and Materials

The video tutorial discusses the construction techniques used at the Proud Green Home, focusing on moisture control and thermal bridging. It covers the foundation's capillary break, slab treatment with vapor barriers and gravel, and the use of exterior cladding and water-resistant barriers. Additionally, it highlights the use of rigid foam insulation to minimize thermal bridging.

What was the purpose of the pre-drywall event at the Proud Green Home?

• To sell construction materials

• To educate consumers and visitors about construction techniques

• To recruit volunteers for the project

• To celebrate the completion of the home

What is the primary function of the capillary break in the foundation?

• To increase the structural strength of the foundation

• To provide additional insulation

• To prevent water from moving inside the home

• To enhance the aesthetic appeal of the home

Why is it important to control moisture at the foundation level?

• To prevent mold growth and structural damage

• To reduce the weight of the building

• To enhance the color of the foundation

• To make the foundation more flexible

How does the gravel under the vapor barrier help in slab treatment?

• It provides a solid base for the slab

• It helps dissipate pressure and prevent water ingress

• It acts as a decorative element

• It increases the thermal resistance of the slab

What is the role of the vapor barrier in the slab treatment?

• To increase the thickness of the slab

• To add color to the concrete

• To prevent moisture from penetrating the slab

• To provide a smooth surface for flooring

What is the purpose of the zip system sheeting used in the exterior cladding?

• To act as a water-resistant barrier

• To increase the height of the building

• To reduce construction costs

• To provide a decorative finish

What material is used between the sheathing and framing members to reduce thermal bridging?

• Fiberglass insulation

• Rigid foam insulation

• Metal sheets

• Wooden panels

How does the rigid foam insulation contribute to the building's energy efficiency?

• By increasing the building's height

• By reducing thermal bridging

• By making the walls more flexible

• By adding weight to the structure
